Mechanisms of the preventive properties of some garlic components in the carbon tetrachloride-promoted oxidative stress. Diallyl sulfide; diallyl disulfide; allyl mercaptan and allyl methyl sulfide.

Research communications in molecular pathology and pharmacology, 1999
Previous studies evidenced that garlic extracts and/or garlic components were able to prevent against chemically induced tumors or acute toxic effects of chemicals (e.g. CCl4 induced liver injury). The chemopreventive potential of garlic has been attributed to the presence in it of several bioactive organosulfur compounds. Those components might act as

Pulsed Laser Copolymerization of Ring-Opening Cyclic Allylic Sulfide Monomers with Methyl Methacrylate and Styrene

Macromolecules, 2002
Two cyclic allylic sulfide monomers, 6-methylene-2-methyl-1,4-dithiacycloheptane (MDTP) and 7-methylene-2-methyl-1,5-dithiacyclooctane (MDTO), were copolymerized with methyl methacrylate (MMA) using the pulsed laser polymerization technique. MDTO was also copolymerized with styrene (STY) under the same conditions.

Significant inhibition of garlic essential oilon benzo[a]pyrene formation in charcoal-grilled pork sausagesrelates to sulfide compounds.

Food Research International, 2021
To addgarlic more conveniently, the substitute-garlic essential oil(GEO)is wildly applied in meat product for flavor improvement. However, the effects of GEOon chemical hazard formation, such as benzo[a]pyrene (BaP), in meat processing have not been ...

Experimental and Theoretical Kinetic Studies of the Ozonolysis of Selected Allyl Sulfides (H2C═CHCH2SR, R = CH3, CH3CH2): The Effect of Nascent OH Radicals.

Journal of Physical Chemistry A, 2022
Rate coefficients of the O3-initiated oxidation of allyl methyl sulfide (H2C═CHCH2SCH3, AMS) and allyl ethyl sulfide (H2C═CHCH2SCH2CH3, AES) were determined at atmospheric conditions by "in situ" FTIR.

Photooxidation Reactions of Allyl Methyl Sulfide Initiated by OH Radicals and Cl Atoms in the Troposphere.

Journal of Physical Chemistry A
The sulfur-containing volatile organic compounds (VOSCs) have a pronounced potential to impact the atmosphere. Hence, studying their photooxidation reactions with tropospheric oxidants has substantial relevance.

Kinetics, product distribution and atmospheric implications of the gas-phase oxidation of allyl sulfides by OH radicals.

Chemosphere, 2021
Relative rate coefficients of the OH radical -initiated oxidation of allyl methyl sulfide (AMS, H2CCHCH2SCH3) and allyl ethyl sulfide (AES, H2CCHCH2SCH2CH3) have been measured at atmospheric pressure of synthetic air and 298 K: kAMS= (4.98 ± 1.42) and ...
